Tried the PSU bit, mine works on another system and when I tried a seperate psu
I ran the system w/o CPU, ram, or peripherals in and have same issue which tells me I have 1 of 2 daunting issues at hand.
Either my CPU took a dump on me or the motherboard's cpu socket is done for.
As I have no other LGA775 platform handy to test the cpu or motherboard I'm at a loss. Intel told me that something like 75% of POST failures are motherboard related and while although believable they are also trying to prevent a rma.
I could RMA both without knowing which is faulty and be w/o a system for who knows how long.
I spent all day searching around town for a shop that would test my CPU but all of the shops had no hardware on site and wanted to charge me a minimum service charge plus charge me to reinstall the cpu into my system which is faulty either way?
what good is it in having a shop if that's how you run things.
I could make a killing if I open a shop here, everyone else is incompetent.
Now I'm stuck with the choice of ordering a cheap mobo or cpu and ordering the a part to replace a part that is or isn't faulty. Or going without anything for weeks and weeks. .......
Once again, I disconnect 12v cpu power, same issue.
I remove all peripherals, same issue.
I swap psu, same issue.
I remove cpu, SAME ISSUE!
Opinions? CPU or motherboard at fault here?
Anyone got an old 775 mobo/cpu combo laying around they'd wanna either let go off or loan to me? I'm dieing after just spending so much time, money, and effort and all I have to show is a very expensive nightlight.

Regardless, I would loosen the block up until you can easily spin it from side to side, but it must still be tight enough to remain in direct contact with the cpu. If the PC boots properly you can then slowly increase the tightness of the block, while powered off. I would monitor the cpu core temperatures and tighten the block until the temperatures stabilize.
If the ^^above^^ doesn't help I would check the socket for bent or damaged pins, dust, lint, hair, paste, etc... You'd be surprised at how easy it is for a little thermal paste to works it's way into the socket.
I did use the back plate, I have reinstalled it twice although I didn't try loosely. Looks like that's my next step.
The plate semed like I would be good at distributing pressure but as I said i'll give it a go, and I did use a tab too much thermal paste first round but I went in and cleaned up a bit, I'll get a magnifying glass and give it a thorough investigation.
Tried water block as loose as possible, no avail, took block off and removed cpu. looked over CPU surface and it appears some pins are close to the outer edge of the copper contact surfaces but since this has been installed multiple times I can't tell whether one pin is missing or not.
Inspected the socket with magnifying glass for 5 minutes and I can't seem to find anything (although I was hoping I would). I cleaned off the previos thermal paste with a q tip lightly dipped in alcohol followed by a paper towel, is it logical the alcohol would've made it's way into the die and killed my proc?
